Guy Norris at Aviation Week reports, “Hydrogen fuel may offer attractive pathways toward the goal of zero carbon emissions, but turning that vision into a practical propulsion system is another matter. Now Pratt & Whitney thinks it may have taken the first steps along that path with the Hydrogen Steam-Injected, Intercooled Turbine Engine (HySIITE) concept—a novel hybrid engine configuration that combines the advantages of the fuel’s cryogenic properties with the thermodynamic benefits of steam injection. Pratt & Whitney has unveiled details of the concept, which has been studied under a two-year $3.8 million U.S. Energy Department Advanced Research Projects Agency–Energy (ARPA-E) effort. While Pratt acknowledges the cycle is complex and requires more study, it is encouraged by the results, which show potential for as much as 35% lower energy use compared with current state-of-the-art engines.”

Eve Air Mobility Brands UATM Solution ‘Vector’
Aviation Week reports, “Eve Air Mobility has chosen the name Vector for its in-development urban air traffic management (UATM) solution, with first deliveries now planned for 2026.” The Embraer spinoff is “the only major air taxi OEM that is also developing a UATM solution, considered critical to enabling high-density operations of drones and electric vertical-takeoff-and-landing (eVTOL) vehicles.”

Aviation Week Article: Airbus Delays Hydrogen But Expands Engine Test Plan
Guy Norris at Aviation Week reports, “Airbus is slowing ambitions to develop a hydrogen-fueled airliner by the mid-2030s but is expanding nearer-term plans to flight test unducted and ducted sustainable aviation fueled (SAF) engines for its next-generation single aisle. Under its ZEROe initiative announced in 2020, Airbus planned to develop a 100-seat hydrogen-fueled airliner for service entry in the middle of next decade, and aimed to flight test supporting propulsion and systems technology on an Airbus A380 later this decade.”
